What are the emerging trends in precast?
Depending on the load-bearing structure of the building, some of the emerging trends in precast systems are:
Large-panel systems: The designation "large-panel system" refers to multistory structures composed of large wall and floor concrete panels connected in the vertical and horizontal directions so that the wall panels enclose appropriate spaces for the rooms within a building.

Frame systems: Precast frames can be constructed using either linear elements or spatial beam-column sub-assemblages. Precast beam-column sub-assemblages have the advantage that the connecting faces between the sub-assemblages can be placed away from the critical frame regions; however, linear elements are generally preferred because of the difficulties associated with forming, handling, and erecting spatial elements.

Slab-column systems with shear walls: These systems rely on shear walls to sustain lateral load effects, whereas the slab-column structure resists mainly gravity loads. There are two main systems in this category:

  • Lift-slab system with walls
  • Prestressed slab-column system

Modular system: In case of smaller single units, this system is helpful. Some of the advantages are;

  • Entire unit is cast in a factory and installed at site.
  • Suitable for toilet blocks or individual rooms
  • Monolithic casting guarantees waterproofing at junctions

In precast, which segment do you cater to the most?
Nuvoco has contributed and provided solutions to the Infrastructure, mainly Mass Rapid Transit System such as the Noida Metro and the Mumbai Metro projects.

Noida metro project: Nuvoco supplied 243,700 CuM of concrete for Noida Metro, for its NC 01 -elevated viaduct and 8 elevated stations, and NC 02 – elevated viaduct and 7 elevated stations. 3 dedicated captive plants were set up for the project with a concrete output of 250 CuM/hr, with one plant for the casting of U girders. The main challenges included on time productivity, de-shuttering and lifting of the precast modules, controlling the temperature and shrinkage, and aesthetic finish. Each of the girders were with the specification of 5 m wide, 27 m long, with a height of 1.8 m, a thickness of 150 – 200mm, and a volume of 50 – 60 CuM. This was pre-stressed, using 52 to 109 cables as per design. Nuvoco used its high performance early strength concrete, Robuste, of M55 Grade, for the project, ensuring the U Girders achieved a strength of 12 – 14 Mpa at 12 hrs for early de-shuttering. As a result, it successfully erected 200 U-shaped girders in May 2016.

Mumbai metro project: The Mumbai Metro Line – 3, connecting Cuffe Parade to SEEPZ, with 26 underground stations and one at-grade station. The requirement was for package 4, that comprised the three underground stations. Nuvoco set up a captive plant at the site, along with a transit mixer, for the production of 2,48,000 CuM of concrete. This was used for the construction of 6082 m twin bored tunnels with a diameter of 5.80 m. The tunnel sections are 1.4 m long, 1 m wide, and 275 mm in height, with a volume of 1.4 m3. Precast was used to provide a protective lining and reinforcement to the structure. The primary challenge was supplying high early strength concrete of 12 Mpa at 12 hrs without steam curing for de-shuttering. Insert. The project also needed to ensure extremely low Chloride penetration and migration to offer a service life of 150 Years, along with controlled shrinkage, and a customised aesthetic finish. Nuvoco has been able to address these needs by using a combination of two of its products, Instante and Robuste, of M50 Grade.

The industry took a leap with smart products in cement. Can you elaborate on the smart product portfolio of Nuvoco?

Quote from Dalmia Cement for World Environment Day

Mahendra Singhi, MD & CEO, Dalmia Cement Bharat Limited, who is best known for being an avid advocate of sustainability, said, "The recent crisis, which impacted the entire world, has brought several dramatic changes to the environment from the past two months with a steep fall in global carbon emissions. We have to now explore how – as per our conscious low consumption practices – we can ensure that this reduction is not transient but results in low carbon economy. This crisis has further made all of us to realise that nature is a source of solace, an inspiration, and a teacher and the utmost need to protect it. This Environment Day, let us all come together and commit ourselves to simplest lifestyles as nature tends to act in the simplest way. I believe we still have the opportunity to reshape and redesign our world in a more. Sustainable way and I urge all global players, to not only work towards creating a greener environment, but also healthy lifestyles for all."

World Environment Day spotlight on innovation and circularity

On World Environment Day, the Indian cement industry reiterated its commitment to supporting India’s climate ambitions through sustainable manufacturing, resource efficiency and the adoption of cleaner technologies.

The Cement Manufacturers’ Association (CMA) said the sector remains aligned with the Government of India’s Net Zero commitments and is accelerating efforts to reduce its environmental footprint while supporting the country’s infrastructure and development agenda.

Parth Jindal, President, CMA and Managing Director, JSW Cement, said the industry is increasingly adopting cleaner technologies, improving energy efficiency and expanding the use of alternative fuels and raw materials. He also highlighted the growing importance of circular economy practices, where industrial by-products and waste streams from one sector are utilised as resources in another.

“The Indian Cement Industry is aligned to the Government’s commitments on carbon mitigation and is accelerating the adoption of cleaner technologies, resource efficiency and circular economy practices while actively exploring the potential of Carbon Capture, Utilisation and Storage (CCUS) as a critical pathway for deep decarbonisation,” said Jindal.

He added that coprocessing industrial waste and by-products helps conserve natural resources, reduce disposal requirements and lower the environmental footprint across multiple sectors.

According to Jindal, sustainability is no longer limited to manufacturing processes but is increasingly influencing investment decisions, innovation strategies and long-term growth plans within the industry.

Echoing similar views, Dr Raghavpat Singhania, Vice President, CMA and Managing Director, JK Cement, said sustainable development extends beyond emissions reduction and must also focus on responsible resource utilisation and waste minimisation.

“Sustainability in the built environment cannot be measured by emissions alone. It is equally about how efficiently we use resources, how effectively we minimise waste and how responsibly we create the infrastructure that will serve future generations,” said Singhania.

He noted that the cement industry is advancing its sustainability agenda through greater resource efficiency, increased circularity, technological innovation and continuous improvements in manufacturing practices. As a key contributor to India’s infrastructure development, the sector has a critical role to play in balancing economic growth with environmental responsibility.

On the occasion of World Environment Day, industry leaders reaffirmed their commitment to supporting India’s climate goals while delivering the materials required for resilient, durable and sustainable infrastructure.

Environmental sustainability requires immediate action, not just long-term commitments and discussions. Recycling, circular economy practices, and technology-driven waste management can help industries reduce environmental impact while supporting sustainable growth.

Author: Jignesh Kundaria, Director and CEO, Fornnax Technology

World Environment Day serves as an important reminder that environmental sustainability can no longer remain confined to discussions, reports, or long-term commitments. The environmental challenges facing the world today demand immediate, measurable, and collective action. Across industries and communities, waste generation continues to outpace our ability to process it responsibly, placing increasing pressure on ecosystems, natural resources, public health, and the well-being of future generations.

One of the most significant shifts required today is a change in how society perceives waste. Rather than being viewed as a material to be discarded, waste must be recognised as a valuable resource that can contribute to both economic growth and environmental protection when managed through the right technologies and systems. This mindset forms the foundation of the circular economy model that countries across the world are increasingly adopting to reduce landfill dependence, recover valuable materials, and create more sustainable industrial ecosystems.

India has made meaningful progress in strengthening awareness around sustainability, recycling, and environmental responsibility over the past decade. Significant efforts are being made to formalise the recycling sector through improved infrastructure, technology adoption, policy implementation, and broader stakeholder participation. These developments are creating a stronger foundation for responsible waste management and resource recovery across the country.

However, achieving long-term environmental impact requires collaboration from all stakeholders. Industries, policymakers, technology providers, and communities must work together with greater accountability to strengthen recycling ecosystems, encourage responsible waste management practices, and create sustainable outcomes through consistent execution rather than temporary interventions.

As someone closely associated with the recycling industry, I firmly believe that technology will play a decisive role in addressing future environmental challenges. Advanced recycling systems have the potential to recover valuable resources, reduce pollution, minimise landfill burdens, and conserve energy, creating a more sustainable future for generations to come. This belief is deeply reflected in Fornnax’s motto, “Committed to Create a Green Future,” which embodies our commitment to building long-term environmental value through innovation and responsible action.

At the same time, technology alone cannot deliver meaningful change. Real progress requires intent, awareness, participation, and a shared sense of responsibility. Sustainable development can only be achieved when innovation is supported by collective action and a genuine commitment to environmental stewardship.

On this World Environment Day, let us move beyond conversations and take meaningful steps towards creating a cleaner, greener, and more sustainable planet. By embracing innovation, strengthening recycling ecosystems, and acting responsibly today, we can create lasting environmental impact and secure a better future for generations to come.
